AWS Weekly Roundup: Anthropic and Meta Partnerships, AWS Lambda S3 Files, Amazon Bedrock AgentCore CLI, and More (April 27, 2026) | Amazon Web Services

Voiced by Polly

In late March, he took me to Seattle for the Specialist Tech Conference, one of the most energizing gatherings of AWS specialists from around the world. It was an incredible opportunity to connect with peers, exchange experiences, and dive deep into the latest advances in generative AI and Amazon Bedrock—and a powerful reminder of something I truly believe: when specialists come together to challenge each other, explore edge cases, and co-create solutions, the impact goes far beyond the boardroom. In a rapidly changing space like artificial intelligence, a strong internal community isn’t a nice-to-have — it’s a competitive advantage.

Now let’s dive into this week’s AWS news…

Anthropic Partnership: Claude at AWS Trainium and Graviton and Claude Cowork at Amazon Bedrock – This week, AWS and Anthropic deepened their product collaboration in a meaningful way for builders. Anthropic now trains its most advanced base models on AWS Trainium and Graviton infrastructure, working directly at the silicon level with Annapurna Labs to maximize computational efficiency from hardware to stack.

Claude Cowork Now Available on Amazon Bedrock – Claude Cowork brings Anthropic’s collaborative AI capabilities directly to enterprise creators within the AWS ecosystem, enabling teams to work alongside Claude as a true collaborator, not just a tool. Now you can deploy Claude Cowork in your existing Amazon Bedrock environment, keep your data safe within AWS, while leveraging the full power of Claude for AI team workflows.

Claude Platform on AWS (coming soon) — A unified environment for developers to build, deploy, and scale applications using Claude without ever leaving AWS. If you’re building with Generative AI on AWS, this is a significant step forward in what you’ll be able to do with Claude directly through Amazon Bedrock.

Meta Signed Agreement with AWS to Support Agent AI on Amazon’s Graviton Chips — Meta has signed an agreement to deploy AWS Graviton processors at scale, starting with tens of millions of Graviton cores, to power CPU-intensive agent AI—including real-time reasoning, code generation, search, and multi-step job orchestration.

Last week’s launch

Here are some news and updates from the past week that caught my eye:

  • AWS Lambda Functions Can Now Mount Amazon S3 Buckets as File Systems with S3 Files — You can now mount Amazon S3 buckets as file systems in AWS Lambda using S3 Files, allowing your functions to perform standard file operations without downloading data for processing. Built on top of Amazon EFS, S3 Files provides the simplicity of a file system with the scalability, resiliency, and cost-effectiveness of S3—and multiple Lambda functions can connect to the same file system simultaneously and share data through a common workspace. This is particularly valuable for AI and machine learning workloads where agents need to retain memory and share state across channel steps.
  • Amazon EKS Hybrid Nodes Gateway for Kubernetes Hybrid Networks – Amazon Elastic Kubernetes now offers an Amazon EKS Hybrid Nodes gateway that automates networking between EKS cluster VPCs and Kubernetes Pods running on EKS hybrid nodes. You can now eliminate the need to route local subnets or coordinate network infrastructure changes, greatly simplifying hybrid Kubernetes environments. The gateway automatically enables pod-to-pod traffic across cloud and on-premises environments, manages cross-tier and webhook communication and connectivity for AWS services such as Application Load Balancers, and is available at no additional charge.
  • Amazon Aurora Serverless: Up to 30% better performance, smarter scaling and still scaling to zero – Amazon Aurora Serverless is just faster and smarter, with up to 30% better performance than previous versions and an improved scaling algorithm designed to handle workloads where multiple tasks compete for resources – such as busy APIs and AI agent applications with long idle windows. Now you can run even more demanding serverless workloads, pay only for what you use, and automatically scale to zero when not in use. All enhancements are available in the version 4 platform at no additional cost.
  • Amazon Bedrock AgentCore adds new features to help developers create agents faster – Amazon Bedrock AgentCore introduces a managed bundle (preview), AgentCore CLI skills, and AgentCore for coding assistants, helping developers move from an idea to a working agent prototype faster. A managed bundle allows you to define an agent by specifying a model, syscall, and tools and start it immediately without the need for orchestration code—and when you’re ready for full control, you can export the bundle orchestration as Strands-based code. AgentCore CLI deploys your agents with infrastructure-as-code management and auditability (AWS CDK today, Terraform coming soon) and is available in 14 AWS regions at no additional charge.

More AWS news

Here are some other posts and resources you might be interested in:

  • Introducing Granular Cost Attribution for Amazon Bedrock – This post introduces you to how Amazon Bedrock’s granular cost attribution works and describes practical examples of cost tracking scenarios. You can now tag and track Bedrock usage costs at a finer level of detail – useful for organizations running multiple teams or projects on Bedrock that need accurate cost visibility and chargeback capabilities.
  • Automating Incident Investigation with AWS DevOps Agent and Salesforce MCP Server — This post (co-authored with Salesforce) shows how AWS DevOps Agent integrated with Salesforce MCP Server automates the entire infrastructure incident investigation lifecycle—from problem identification and root cause diagnosis to customer notification via Salesforce Service Cloud. It’s a compelling real-world example of how AI agents and MCP-based tool connectivity are reshaping DevOps workflows in production, dramatically reducing mean time to resolution.
  • AWS microcredentials are now free — Here’s why it matters — You can now access AWS microcredentials for free through AWS Skill Builder in all countries where the platform is offered. Unlike traditional multiple-choice certifications, microcredentials are hands-on assessments that put builders in simulated business scenarios where they configure, troubleshoot, and optimize right in a live AWS environment—the same way they would at work. A great opportunity to test real cloud skills without a cost barrier.
  • Amazon SageMaker AI now supports optimized recommendations for generative AI – You can now use Amazon SageMaker AI to automatically identify optimized deployment configurations for your generative AI models, including instance type, container, and inference parameters. This new feature takes the guesswork out of tuning your inference infrastructure, helping you reduce costs and improve the latency of your AI applications in production.
